Troubleshooting

  • Open WebUI can’t connect → use host.docker.internal from Docker on macOS.
  • Model load stalls → check ollama ps and free memory.
  • Agent replies are off → adjust the prompt and system roles in the UI.

Swap components

  • Use Llama.cpp if you want pure local GGUF fallback.
  • Add qdrant to build a private RAG knowledge layer.
